From CloudModding TWW Wiki
This wiki aims to document the multitude of formats found throughout The Legend of Zelda: The Wind Waker in one place. At this point in time, we intend to transfer and expand upon the information from a wiki written mainly by Gamma/Sage of Mirrors on a repo of WindEditor written by LordNed to this wiki.
